In 2008, more x86-64 systems adopted UEFI. While many of these systems still allow booting only the BIOS-based OSes via the Compatibility Support Module (CSM) (thus not appearing to the user to be UEFI-based)

if wikipedia isn't wrong (which it probably is to be fair) everything since 200 fucking 6 is uefi-based but we didn't know about it because they just did this

actually i wonder if this is the reason why lga 775 boards are so fucking wonky about everything

Makura @makura@gts.makura.top

@jeder to be fair, on most modern hardware youre able to boot only EFI OSes from internal storage

CSM is reserved for anything external

@makura i mean nowadays you can't even use CSM

Makura @makura@gts.makura.top

@jeder yeah you can only disable it for external media

@jeder article also says

In October 2017, Intel announced that it would remove legacy PC BIOS support from all its products by 2020, in favor of UEFI Class 3.[118] By 2019, all computers based on Intel platforms no longer have legacy PC BIOS support.

so it took quote some years to fully get rid of it

@eloy yeah
but yeah
i mentioned it like twice already but i really wonder if the reason why lga 775 boards were wonky with settings was that they were pretty much the testing grounds of uefi

@eloy (pretty much every time i set my p43 board to use AHCI i have seen it revert to IDE few days later for some reason)

@jeder I have no idea
